In 2019, the Áspero revolutionized the gravel riding scene, marking the beginning of a "new era of speed in gravel." While maintaining its fun yet intense character, the latest Áspero has been updated with several enhancements including a threaded bottom bracket, cleaner cable routing, and a Universal Derailleur Hanger compatible with SRAM’s Transmission drivetrains. It’s also been designed to be more aerodynamic. For the Áspero, aerodynamics focus more on conserving energy rather than just cutting speed due to reduced drag. The modest energy savings of three watts after battling a headwind all day could mean consuming one fewer energy gel—a worthwhile benefit.

Further improvements include lowered seat stays for increased rear compliance and a slight reduction in front-end stiffness, easing the strain during the final hours of a long race. Additional clearance for mud was also incorporated, drawing on lessons from the R5-CX and the muddy conditions at Unbound 2023. These may seem like minor adjustments, but collectively, they significantly enhance the bike's performance. The outcome is a model that stays true to the original Áspero's essence but offers greater speed, comfort, and versatility.

The SRAM Apex XPLR AXS 1 component group is a cutting-edge, wireless drivetrain designed specifically for gravel and adventure bikes. This groupset emphasizes simplicity and efficiency, enabling a streamlined setup through the use of SRAM's AXS wireless technology. By removing the need for physical shift cables, the Apex XPLR AXS ensures precise and reliable shifting performance under any conditions.

It features a 12-speed rear derailleur with a wide-range, 10-44 tooth cassette, providing a broad gear range that is perfect for varied terrain encountered in gravel riding. The derailleur includes SRAM’s clutch mechanism which maintains tension in the chain to prevent drop-offs and reduce slap, enhancing ride smoothness and chain stability. The simplicity of the single front chainring setup not only reduces weight but also minimizes the potential for mechanical issues while improving aerodynamics.

The Apex XPLR AXS levers are ergonomically designed for comfort and intuitive use, with textured hoods for better grip in wet conditions. Hydraulic disc brakes are included, offering superior stopping power and control, which is crucial for the unpredictable surfaces of gravel paths. This groupset represents an ideal combination of technology, functionality, and durability for the modern adventure cyclist.
